Idling fan

ABSTRACT

An idling fan includes a blade fan mounted on an eccentric shaft of a vibrating motor in an electronic device, such as a controller for a TV game. The blade fan rotates along with the eccentric shaft to produce airflows when the vibrating motor is actuated, and the produced airflows quickly carry away heat generated by the electronic device during operation thereof.

FIELD OF THE INVENTION

The present invention relates to an idling fan, and more particularly to an idling fan including a blade fan mounted on an eccentric shaft of a vibrating motor in an electronic device to rotate along with the eccentric shaft and produce airflows, which quickly carry away heat produced by the electronic device during operation thereof.

BACKGROUND OF THE INVENTION

Some very common electronic devices, such as the controller of a TV game, the mobile phone, etc., all have a vibrating motor mounted therein. The vibrating motor includes an eccentric shaft that is rotated by the motor to generate vibration, so as to remind a mobile phone user of an incoming call, or bring a TV game player to go through a scene created by the TV game software. While the electronic device generates heat during operation thereof, there is not a proper way for dissipating the generated heat.

It is therefore tried by the inventor to develop an idling fan for mounting on the eccentric shaft of the vibrating motor in the heat-producing electronic device to produce airflows and thereby carry away the heat generated by the electronic device.

SUMMARY OF THE INVENTION

A primary object of the present invention is to provide an idling fan for mounting on the eccentric shaft of the vibrating motor in the heat-producing electronic device, so that the fan rotates along with the eccentric shaft to produce airflows when the vibrating motor is actuated to rotate the eccentric shaft.

To achieve the above and other objects, the idling fan according to the present invention includes a blade fan mounted on an eccentric shaft of a vibrating motor in an electronic device, such as a controller for a TV game. The blade fan rotates along with the eccentric shaft to produce airflows when the vibrating motor is actuated, and the produced airflows quickly carry away heat generated by the electronic device during operation thereof.

BRIEF DESCRIPTION OF THE DRAWINGS

The structure and the technical means adopted by the present invention to achieve the above and other objects can be best understood by referring to the following detailed description of the preferred embodiments and the accompanying drawings, wherein

FIG. 1 is an exploded perspective view of a vibrating motor having an idling fan of the present invention mounted thereon; and

FIG. 2 is an assembled perspective view of FIG. 1.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Please refer to FIGS. 1 and 2 that are exploded and assembled perspective views, respectively, of a vibrating motor 11 having an idling fan of the present invention mounted thereon. The vibrating motor 11 is configured for an electronic device, such as a controller for a TV game, a mobile phone, a personal digital assistant (PDA), etc., and includes an eccentric shaft 13. The idling fan of the present invention includes a blade fan 15 mounted on the eccentric shaft 13 of the vibrating motor 11. When the vibrating motor 11 is actuated to rotate the eccentric shaft 13 and thereby generate vibration, the blade fan 15 rotates along with the eccentric shaft 13 to produce airflows.

When the electronic device is in use, the vibrating motor 11 operates and the blade fan 15 is brought by the eccentric shaft 13 of the motor 11 to rotate and induce airflow into the electronic device to quickly carry away heat produced by the electronic device during operation thereof.

In an embodiment of the present invention, the electronic device is a controller of a TV game (not shown). The controller of the TV game includes a pair of joysticks for gripping by a user. The vibrating motor 11 is mounted on the controller, and the blade fan 15 is mounted on an eccentric shaft 13 of the vibrating motor 11. When the vibrating motor 11 is actuated to rotate the eccentric shaft 13, the blade fan 15 rotates along with the eccentric shaft 13 to produce airflows, which quickly carry away heat produced by the controller of the TV game.

The controller of the TV game is also provided with at least one set of arrow keys (not shown) for the user to manipulate the TV game in up, down, right, and left directions, and a plurality of control keys for the user to input different control instructions. Through the arrow keys and the control keys, the user may control and play the TV game.

The present invention has been described with a preferred embodiment thereof and it is understood that many changes and modifications in the described embodiment can be carried out without departing from the scope and the spirit of the invention that is intended to be limited only by the appended claims. 

1. An idling fan, comprising a blade fan mounted on an eccentric shaft of a vibrating motor mounted in an electronic device, such that said blade fan rotates along with said eccentric shaft of said vibrating motor to produce airflows when said vibrating motor is actuated to rotate said eccentric shaft, and the airflows produced by said blade fan being adapted to quickly carry away heat produced by said electronic device during operation thereof.
 2. The idling fan as claimed in claim 1, wherein said electronic device is a controller for TV game.
 3. The idling fan as claimed in claim 1, wherein said electronic device is a mobile phone.
